马尔可夫毯-系统和环境之间的统计独立性-已成为流行的贝叶斯认知的观点下描述生活系统的边界。马尔可夫毯背后的直觉源于对非循环、非时态网络的考虑。相比之下，生命系统表现出经常性的非平衡相互作用，在系统和环境之间产生普遍的耦合，使得马尔可夫毯非常不寻常，并仅限于特定情况。（2021）打破了目前关于马尔可夫毯在划分生命系统与环境之间边界方面的作用的争论。作者准确地描述了马尔可夫毯之间的差距作为一个有用的属性统计推断和本体加载的概念在FEP，作为一个边界内发生贝叶斯推理。虽然目标文章所追求的论点是正确的和重要的，我们认为，一个根本的问题仍然没有得到解决，因为该文件默认（通常FEP），马尔可夫毯可以在很大程度上确定的基础上的系统的结构连接（而不是其功能连接）。
Markov blankets–statistical independences between system and environment–have become popular to describe the boundaries of living systems under Bayesian views of cognition. The intuition behind Markov blankets originates from considering acyclic, atemporal networks. In contrast, living systems display recurrent, nonequilibrium interactions that generate pervasive couplings between system and environment, making Markov blankets highly unusual and restricted to particular cases.In the target article, Bruineberg et al.(2021) disrupt current debates about the role of Markov Blankets in demarcating the boundaries between living system and their environment. The authors accurately describe the gap between a Markov blanket as a useful property for statistical inference and the more ontologically loaded concept in the FEP, as a boundary within which Bayesian inference occurs. While the arguments pursued by the target article are both correct and important, we think that a fundamental concern remains unaddressed as the paper tacitly accepts (as generally the FEP does) that Markov blankets can be identified largely on the basis of the structural connectivity of a system (as opposed to its functional connectivity).
